IMFRGVEMENI IN $TILLS FOR SPIRITS, 8:0.

Specification forming part of Letters Patent No. 115,751, dated June 6,1871; antcdatcd June 2, 1871.

To all who-m it may concern:

Be it known that I, WESLEY MAKELY, of the city and county of Alexandriaand State of Virginia, have invented certain new and useful Improvementsin Stills; and I do here by declare the following to be a full, clear,and exact description of the same, reference being had to theaccompanying drawing forming part of this specification, in which myinvention is represented by a longitudinal vertica section.

The object of this invention is to prevent fusil-oil and other volatiledeleterious substances from passing over with the spirits. This objectis accomplished by the introduction of a refrigerating coil between thestill and the worm-pipe for the purpose of cooling the spirituous vaporssufficiently to precipitate the i'usil-oil contained in them withoutc011- den sing the spirits, the latter thus purified and separated beingleft to pass over alone.

In the drawing, Am the charging-tub; B, the still; 0, the worm-tub; D,the doubler; E, the pipe lea-ding from the still to the doubler; F, thepipe leading from thedoubler to the worm; G, the low-wine tub; H, thelowwine pipe; I, the tube used to discharge the several upper chambersof the doubler; and J, the return-pipe leading from the lower chamber ofthe doubler back to the still. All these are of any of the usual forms,and are not claimed as constituting my invention, which relates solelyto the device employed in connection with them as separator andpurifier, which I will now proceed to describe. This device consists inthe employment of a refrigerating coil, M, in one of the vapor-chambersof the still or doubler, preferably the latter, through which may bepassed a constant stream of water of any required temperature, so thatchamber may be controlled at will. In the drawing, on indicates thesupply-pipe; m, the

waste-pipe of the coil; and c c are cocks, by which means the currentflowing through the coil maybe retarded or accelerated, as desired.

The supply-pipe may be fed both from a hotwater and a cold-water pipe,if preferred, for the purpose of further and more completely controllingthe temperature created by the coil.

A coil is, self-evidently, only one form of cooler, and is employedbecause believed to be, for this purpose, superior in simplicity,cheapness, and ediciency to other possible forms.

Instead of this form a water jacket might be used, surrounding thedoubler, or a portion of it; or a water-chamber within the doubler mightbe substituted.

The invention consists not so much in the particular details ofconstruction shown as in the employment of the cooler so constructed andoperating that by means of it the distiller can, at pleasure, reduce thetemperature of the vapor, just before it passes to the worm, to a point,say, from 140 to 150 Fahrenheit, at which temperature fusil-oil and manyother impurities will be condensed and precipitated, while thespirituous vapor will pass along to be condensed in the worm.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

A cooler, M, when employed in connection with a still, substantially inthe manner and for the purpose specified.
